Subject: [PATCH] docs: Move the python libraries to tools/lib/python

"scripts/lib" was always a bit of an awkward place for Python modules.  We
already have tools/lib; create a tools/lib/python, move the libraries
there, and update the users accordingly.

While at it, move the contents of tools/docs/lib.  Rather than make another
directory, just put these documentation-oriented modules under "kdoc".
